iPhone 6+ won't backup to iCloud
I tried to back up my iPhone 6+ to iCloud but didn't have enough space. I then paid for the 50GB storage plan but it still won't backup (and only 4.5 GB used). When I tap Backups it says I have 1 backup, but shows 0 KB. Is my phone just too old? (I have a 13 on order)
